Using a 1000mah Ni Cad instead of 800mah Ni Cad?

[blurredvision]

I just got an RC car, thanks to the kid still inside of me, and am having trouble finding a battery for the damn thing. I bought one at WalMart, but not knowing anything, I bought a NiMH instead of a Ni Cad. Imagine my suprise after charging the sucker that it didn't fit.

Well, my local Radio Shack has a 9.6v Ni Cad battery with charger, exactly what I need, but it's a 1000mah battery. The manual that came with the car says to not use anything higher than 800mah, or it could prematurely burn out the motor in the car. Is a 1000mah that big of a jump, and would it actually burn out the motor?

I think you'd be fine...

mah?

mah = milli amp hours

mAh shouldnt matter, thats just how long it lasts. mA however, is current, and too much could be bad.

 

[Bootprint]

It should be okay, the higher mAh just means it should run a little longer, the voltage is the same...

That is a load of BS. As long as the voltage is within specs you are OK. the mAh rating just indicates the capacity. Bigger = longer life.
youy might want to check that the charger can charge NiMH cells correctly. They are slightly different than NiCd

Bingo. mAh is just a measure of battery capacity. If the battery passes a current higher than the current for which the car was designed though...

Basically, 800 mAh means that the battery can deliver 800 milliamps for one hour. Or one milliamp for 800 hours. 1000 mAh means that the battery can deliver 1000 milliamps for one hour, or 1 milliamp for 1000 hours. So for a given current draw, the 1000 mAh battery will last longer.

It will be fine.

I agree (I sell batteries for a living) the mAH is what is going into the battery, not what is coming out. The higher the amperage, the more time you will get out of the battery, but if it gets too high, generally the battery will be bigger.

Well, here is what the manual says, quote for quote:

"If you purchase a Ni-cad pack from a hobby store, DO NOT select one with a value greater than 800ma/hour. Using Ni-cad batteries higher than 800 ma/hr may cause premature burn out of your electric motor."

Is mah not the same as ma/hour?

The kid inside of you says RC car, but the man inside of you should be saying 1/6 scale gas powered monster

YES, I would love to have something like that, but there's 2 things stopping me: I'm cheap and my woman would kill me.

 

[screw3d]

Get more batteries here?. They have a good resource on batteries too.

It's the same, but there might be something inherent in NiCd batteries that causes higher mAh rated batteries to have a higher amperage output as well.

I don't think so.. voltage is voltage.

The device will only pull as many mA as it requires. It shouldn't matter if the battery can supply more.

It's the same with wall-wart adapters. You can use one thats rated for more than the device requires as long as the voltage is the same.

 

[blurredvision]

Thanks a lot guys. I guess I will pick it up later tonight. I didn't think it would cause a problem, because sometimes they just have to put that stuff in there for legal reasons maybe. Thanks again.

Just run the damn thing.

If it DOES burn up, get a new hotrodded motor from Tower Hobbies. It won't, so you won't have to worry anyhow.

The reason they tell you not to use more than 800 mah packs is not because it puts out too much, but for too long. It will excede the duty cycle of the motor (On time ??? minutes -=- Off time ??? minutes)

Ahhhh... Didn't think of that. I bet that's the case.

It's not going to be a big deal though.

Man... grow up... quit playing with them batteries operated thingy... get a real RC Car already. You know, nitrous burning, corners skidding, adrenaline pumping racing action.

Is this unit done in hina or Korea or some other non-english speaking place?
What I mean is: The translation to english seems to be effed up.
